Soil preparation
The soil should be disinfected before planting. If possible, the soil can be screened through a sieve, and the larger soil blocks and stones can be cleaned up, and then the soil can be reconfigured p>
The pot soil planted can be exposed to the sun, or sprayed with potassium permanganate, formalin, dixone, etc. in an appropriate proportion of aqueous solution, and can be used after drying p>
Budding
It is best to treat the seeds before planting, which can improve the germination rate of seeds. The simplest way is to soak in warm water for 6 ~ 8 hours. You can add some rooting powder and sow after germination p>
Sow
After the seeds are treated, spread the seeds evenly on the soil surface, not too dense, so as not to affect the germination rate of the seeds p>
Then cover the soil surface with a layer of 3mm sandy soil. Don't cover the soil block. It's too heavy. Pour water through and cover with plastic film to moisturize. Move to the sun. If you see that the plastic film is full of water vapor, you can turn on the ventilation and germinate in about 7 ~ 10 days p>
Maintenance
The best germination temperature of Phlox seedlings is 20 ~ 22 ℃, and the soil temperature also has a great impact on the seeds, and the temperature should not be too low. After emergence, the temperature can be appropriately reduced to 15 ℃, and a slightly lower temperature can form a good plant type and promote its growth p>
After emergence, careful management should be carried out, and attention should be paid to water control and light supplement to avoid the growth of seedlings. When the seedlings grow to 6 ~ 7 cm, they can be transplanted. Note that the seedlings of Phlox are not resistant to transplanting, do not toss repeatedly, and ensure that the roots are intact during transplanting p>
